Mount Puntino with spacers!
Move filter wheel to OPEN position!
Moved focal plane back 1.7 inches by installing spacer mount SH with TOP towards CCD controller should use metal spacers if possible to allow guider to focus! star at (680,320) in guider at guideloc 1500, INST 2 puts star in SH at INST 1 after GOFFSET 50 0 (so 630,320!) set rotator at approx 10-alt to get spiders diagonal: positive x offset moves dots down positive y offset moves dots right S tilt --> +x N tilt --> -x W tilt --> +y E tilt --> -y
focus around -2000 guidefoc 300 star at (680,320) in guider at guideloc 1500, INST 2 puts star in SH at INST 1 set rotator at approximately 20-alt then: positive x offset moves dots to the right positive y offset moves dots up N tilt --> +y S tilt --> -y W tilt --> +x E tilt --> -x

reference 28 taken as test reference 29 taken just before sunset saw relatively poor SH results with coma and spherical, and astigmatism jiggled primary --> coma changed significantly moved secondary to remove coma, and spherical seemed to improve moved tertiary to remove astigmatism, and spherical seemed to improve looked at range of altitudes in the east, and coma didn't change by too much ended up at xtilt 0.02, ytilt -0.54, tertiary 31900
reference 26 taken as test reference 27 taken just before sunset 120226 595,575 at inst=2 590,585 185-... moved star, moved focus to more position (hit guider range) 193 new star at higher alt put in 1.375 (2 wood + 1 metal), move guider to opposite end of range (0), focus much more negative (~-6000) no chance of guiding 196 still not in focus, actually maybe this is good! worked on centering, see 212 213 moved focus -50 214 df 25 to focus=-5325, very nice changed PA by 20 degrees --> Looks like moving back 1-1.25 inches will be good!

Procedure:
set filter to open position
GOTO 170,alt with INST=2, guideloc 1500
move star to 660,380
inst=0, find guide star and star guiding
Determine PA to align spiders to diagonal
pa=20, rotator=-48 at alt=68
rotate=-15 at alt=35
rotator=20-alt
(figure out which direction in guider corresponds to which direction in SH)A
goffset +x moves SH image right
goffset +y moves SH image up
Center image and guide
Focus
Take several mirror images
Adjust xtilt and ytilt seperate to determine effects on coma
